1,1-Diamino-2,2-dinitroethylene (DADNE) has been considered to be the promising energetic material because of low friction and impact sensitivity than RDX, widely used as a military explosive. DADNE was recorded the powerful detonation characteristics in spite of the same stoichiometric coefficient of RDX. In the present study, we carried out the batch crystallization of DADNE in binary mixture of N,N-dimethylacetamide (DMA) and H2O. Key operating parameters were cooling rate, solvent composition, and saturation temperature to obtain the affordable properties improving packing density and mechanical strength of the DADNE particles. Firstly, we polythermally measured the solubilities of DADNE in a different mass ratio of DMA and H2O at 20 oC ~ 90 oC. Various experiments were conducted to find the optimal combinations of the crystallization parameters to prepare DADNE particles with the average diameter of 5 to 30 micrometer. |
